SLIDE BUCKLE Filed March 17, 1931 JEIHN H DUMKEE Patented Feb. 23, 1932UNITED STATES PATENT OFFICE JOHN H. DOMKEE, OF WEST HAVEN,CONNECTIGWITT,ASSIGNOR TO THE WIRE NOVELTY MANUFACTURING COMPANY, OFWlif'l HAVEN, CONNECTICUT, CORPORATION OF CONNECT IGU'I' sLInn BUCKLEApplication filed March 17, 1931. Serial No. 523,217.

This invention relates to that class of buckles known as slides and usedfor adjusting the length of looped straps, webbing and the like, withoutthe penetration of the material by a buckle part.

The invention about to be described is an improvement upon the devicedisclosed by the Letters Patent Numbered 1588,66 1 and issued to thesame applicant January 13, 1931. The device thus disclosed was a slidebuckle comprising a rectangular frame having mounted thereon a fixed orsliding intermediate bar split into strands integrally connected at bothends and both of the strands being formed to together provide spacedhumps projecting out or the buckle plane in opposite directions. Such aform of intermediate bar was intended to be distinguishable from theintermediate bar structure comprising two bars as disclosed in anearlier patent Numbered 1,762,263 and issued to the same applicant June10, 1930, the structure there being a pair of loops connected at oneside and tree at the opposite side, the intermediate bars integrallyextending from the tree side across the buckle to the connected side,the peaked humps of one bar alternating with the peaked humps of theother bar to provide spaced peaked humps projecting out of the plane ofthe buckle in one direction and also spaced peaked humps projecting outof said plane in the opposite direction. The device herein disclosedhowever is of the single intermediate bar type but comprises abifurcated end portion of a piece ofwire of which the slide buckle ismade, the end portion of the wire being split into strands integrallyconnected at one end, the strands being formed out of the buckle planeto provide spaced humps as in the said previous patents, and thereforethe objects of the invention are to provide a reversible slide bucklehaving a single intermediate bar formed with spaced humps projecting inopposite directions at the same spaced intervals andalong planesperpendicular to the plane of the buckle; and to provide a slide buckleof wire structure the wire ends of which are secured to thestructurewithin the plane of the buckle. With these and other objects in view asmay become apparent from the within disclosures, the inventlon consistsnot only of the particular form 7 herein pointed out and illustrated inthe drawings, but readily admits of certain modifications within thescope of what hereinafter may be claimed. The character ofthe inventionmay behest understood by the reference to one illustrative deviceembodying the invention and illustrated by the accompanying drawings inwhich the Figure 1 is an upright elevationof the device; and the Figure2 is a cross-section upon the dotted line 22 of the previous figure.

The device, as illustrated, is made of wire in a single piece of whichan end portion is bifurcated by means of a split longitudinah ly madetherein a substantial distance to provide the strands 1 and 2 integrallyconnected at one end at which end thewire is then bent at substantiallyright angles to provide the side portion 3, and again bent atsubstantial- 1y right angles to provide the upper horizontal bar 4substantially parallel to the strands 1 and 2 of the bifurcated portion,the wire being again bent at substantially right an les to provide theside bar 5 engaged by the rec endsot the strands 1 and 2, the wire beingagain bent at substantially right angles to provide the lower bar 6substantially parallel to the upper bar 1, and the wire end being bentat substantially right angles to provide the side portion 7 insubstantially longitudinal alignment withthe side portion 3, the wireextremity engaging within the plane of the buckle the bent portion 8 ofthe wire structure, the bifurcated portionof the wire providing theintermediate bar 9 of the slide buckle. in forming the intermediate bar9, the strands 1. and flare independently made in undulating form withrelatively staggered high points projecting out of the plane of thebuckle, each strand being immediately bent, as at 1.0 and 11, inopposite directions out of said plane, and angularly bent and returned,at 12 and 13, relatively crossed, as at 14, angularly rebent andreturned, as at 15 and 1G, and recrossed, as at 17, and angularly rebentand returned, as at 18 and 19, andrecrossed, as at20, and so onthroughout the length of the strands 1 and 2 thereby providing spacedpeaked humps, as for instance at 13 and 19, projecting in one and thesame direction out of said plane, and, as at 12 and 18, projecting outof said plane in one and the same direction opposite to that of thehumps 13 and 19, as better illustrated by the Figure 2, the engagingmetal surfaces of the free ends of the strands 1 and 2 and the side bar5 being united in permanent intimate union, as by welding, brazing or bysoldering as at 21, and the engaging metal surfaces of the wireextremity and the structure at the bend 8 being likewise united inpermanent intimate union, so that in neither instance can the originalcharacter of the surfaces so united be restored by any means effectingthe mere separation of the parts, the slide buckle thus being made rigidand indestructible. The distance of the projections out of the buckleplane in one direction equaling the distance of the projections out ofsaid plane in the opposite direction, the slide buckle is reversible inuse in that the buckle may be turned completely around from the positionillustrated by the Figure 1 so that the upper bar 4 may be in theposition of the lower bar 6, or so that the side bar 5 may assume theposition of the opposite side portions 3 and 7. The spaced humps 13, 19and like humps projecting from the buckle plane in one direction, andthe spaced humps 12, 18 and like humps projecting from said plane in theop posite direction, provide an acute detour for a strap threaded intothe slide buckle in a manner already known to the art. The humps 15, 16and like humps, although not projecting out of the buckle plane, areformed like the humps 12, 13, 18 and 19, in planes perpendicular to thebuckle plane, as illustrated by the Figure 2.

, I claim:

1. A reversible slide buckle comprising a frame having horizontal upper,lower and intermediate bars and side structures, the intermediate barbeing split into strands integrally connected at one end, and peakedhumps provided by both strands, the peaked humps of one strandalternating with the peaked humps of the other strand to provide spacedpeaked humps extending in one dimotion along planes perpendicular to theplane of the buckle and also spaced peaked humps extending in theopposite direction along said perpendicular planes.

2. A reversible slide buckle comprising a rectangular frame havinghorizontal upper, lower and intermediate bars and side struc tures, theintermediate bar being split into strands integrally connected at oneend, the strands being first bent out of the plane of the buckle, eachin opposite directions, and each strand being further bent, relativelycrossed and recrossed to together alternately provide spaced peakedhumps extending in both repeatedly,

directions along planes perpendicular to the buckle plane.

3. A slide buckle of rectangular form having horizontal upper, lower andintermediate bars and side structures, the intermediate bar being splitinto strands integrally connected at one end, the strands beingangularly bent at intervals, the angular bends of one strand whichtogether provide spaced peaked humps projecting in opposite directionsout of the plane of the buckle.
